constrain() - piirab v\u00e4\u00e4rtust teatud vahemikku. Kui v\u00e4\u00e4rtus on v\u00e4ljaspool vahemikku, m\u00e4\u00e4ratakse see l\u00e4hima piirini.
constrain(x, a, b)<\/strong>
x - the number to constrain
a - the lower end of the range.
b - the upper end of the range.
Random(): - genereerib juhusliku t\u00e4isarvu. Saate m\u00e4\u00e4rata numbrivahemiku, millest valitakse juhuslik v\u00e4\u00e4rtus.
